| 摘要: 本工作合成、表征了一系列辅酶B12模型化合物RCo(Salen)L,其中R=CH3,C2H5,n和i-C3H7,n和i-C4H9,研究了上述配合物固体和溶液的Co-C键稳定性,结果表明:固体配合物Co-C键断裂的温度受烷基位阻影响,它们具有以下顺序:CH3>C2H5>n-C3H7≈n-C4H9≈i-C4H9≈i-C3H7.此外还确定了影响配合物Co-C键在溶液中稳定性的因素. |

| Abstract: A series of RCo(salen)L(R=CH3, C2H5, n and i-C3H7, n and i-C4H9)were synthesized and characterized. The stabilities of Co-C bond of title complexes in solid state and in solution was studied. The obtained results showed that the cleavage temperature of Co-C bond of complexes in solid state was effected by the steric bulk of alkyl groups in the following order: CH3>C2H5>n-C3H7≈n-C4H9≈i-C4H9≈i-C3H7. The factors that influenced the stabilities of Co-C bond of complexes in solution were ascertained. |
